Stopped by 3 other parts stores today. 2 said banjo bolts for those calipers not available.
O'Rileys had the Dorman part in stock.

They are just 3/8-24 banjo bolts. What's with that? Maybe a special length????

Anyway they wouldn't fit. Had tried other 3/8-32 at the parts store, 1/2 turn and bind up. Thread pitch seemed off.

Put some sticky grease on a tap and ran the threads. Now they work great. 2 calipers with bad threads????
